Pregnant ??

Hello! So I’m kind of new to this and I hope I can get some answers from all of you lovely ladies.☺️

I been on birth control for almost 6 months now , and while having sex with my boyfriend he never came inside, but 3 weeks ago he did, and is been a week since I been feeling morning sickness, bloated stomach and a little of tender breast. It might be possible that I’m pregnant even tho I take my birth control every day at the exact time.

Also lately I been having so much stress and I read something about high levels of stress can make birth control fail?

I’m worry as my period is supposed to come in 2 weeks.

I hope my doubts sound that stupid for you all, and thanks for the answers in advance!!
